4- Claims.

This invention relates to improvements in replaceable shoe heels and has for its object to provide an improved resilient, durable and replaceable shoe heel that will be highly serviceable and practical in every respect.

The primary object of the present invention is to form an improved shoe heel by providing a plurality of substantially narrow resilient strips and transversely arranging said strips in a depressed member that is formed into the shape of a 'heel and which is capable of being detachably fastened onto the heel portion of an ordinary shoe.

Another object of the invention is to form a portion of the strips from rubber or a suitable resilient composition and another portion of the strips from a harder material, such as leather, and to interpose the leather strips between the rubber strips and to provide means for detachably holding all the strips together.

Another object of the invention is to form the rubber strips of a greater thickness than the leather strips.

Another object of the invention is to construct the depressed member that holds the strips from sheet metal and to form said depressed member of a depth that is less than the thickness of the rubber strips.

The invention further consists in the particular construction, combination and association of the` different parts, such as described in the follow- 21.

invention that is illustrated in the drawing accompanying and forming part of the specification.

It is to be understood that it is not intended to limit the invention to the embodiment shown by said drawing and description and that Variations can be adapted withinthe scope of the invention as set forth in the claims. 4

In the accompanying drawing:

Fig. 1 is a bottom plan assembly view of one of the improved shoe heels and illustrates the fundamental principle of the invention;

Fig. 2 is a bottom plan view of the container that holds the strips which form the body of the heel;

Fig. 3 is a longitudinal side elevational View of the heel shown in its standing position;

Fig. 4 is a central vertical longitudinal sectional view of the heel shown in its standing position;

Fig. 5 is a front elevational view of the improved heel;

Fig. 6 is a bottom sectional plan View taken on the line 6 6 of Fig. '7, with the strips removed and showing a modified form of container with an angular edge for lholding the strips which form the body of the heel; and

Fig. '7 is a central vertical longitudinal sectional view of a modified form of the invention, as illustrated in Fig. 6, showing the resilient strips mounted thereinfthat are adapted to interlock into each other.

Referring in detail to the drawing and the different parts thereof, wherein like reference numerals designate like parts throughout the various views, the numeral I0 designates a plurality of resilient strips that are preferably made of rubber or a suitable resilient composition, and the numeral I2 designates a plurality of more rigid strips that are made from material, such as leather, but can be made from wood or any other suitable material. The said strips I0 and I2 are cut to size and are shaped to conform with a heel-shaped container, as shown in Fig. 1, said container being preferably formed of sheet metal and comprising a flat horizontal face I4 having an extending edge I5 that is bent inwardly at the front portion thereof, as shown at I6 and I1, and is provided with a front end cover I8 that is fastened to the inwardly bent portions I6 and I1 by suitable screws I9, as shown in Fig. 1.

It will be observed that the more substantial strips I2 are less in width and thickness than the resilient strips ID and that space 20 is thus formed between the resilient strips, as shown in Fig. 3, and, also, that the sides of the strips are tapered and are wedged together in the container. A pair of tie rods 2I and 22 is fastened into the extending edge I5 of the container and projects through the strips I0 and I2 and the front end cover I 8; and the said cover and all the strips are held tightly together by lock nuts 23 and 24 which are threaded onto said tie rods 2| andl 22. A plurality of small holes I I is provided through the horizontal face I4 of the container to enable the same to be substantially fastened onto the heel portion of a shoe.

The modified form of container, shown in Fig. 6, comprises a flat horizontal face 25 having an extending edge 26 that tapers inwardly, as shown at E in Fig. 7, and terminates at the front end portion of the container for enabling an end cover 21 to be slidable along the horizontal face 25, said cover being slidably supported onto three tie rods 28, 29 and 30 and held against the resilient strips 3l by the lock nuts 32, as shown in Fig. 7. The strips 3l are formed angularly, as shown in Fig. 7 and thus interlock into each other and are substantially held within the inwardly tapering extending edge 2G by the front end cover 21 that can be tightened against the strips 3l by the lock nuts 32. The holes 33 are for the purpose of enabling the container t'o be nailed onto the heel portion of a shoe.

From the foregoing description, considered in conjunction with the accompanying drawing, it will readily be seen that the invention eliminates the necessity of requiring new heels to be put onto shoes by a Shoemaker, as any or all the various strips can be easily replaced in the event of wear, and, further, heels constructed in accordance with the invention will have an improved resiliency due to the forming of the strips from different materials and the manner in which said strips are relatively arranged.

It is to be understood that the forms of my invention herewith shown and described are to be taken as preferred examples of the same and that various changes relative to the material, size, shape and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claims.

Having thus described my invention, I claim:

l. A replaceable shoe heel comprising a deparallelism therein, a plurality of oblong strips u of a harder material than the rst-mentioned strips interposed between the first-mentioned strips, said strips of the harder material having a width and thickness that is less than the width and thickness of the resilient material, and means for detachably fastening said strips to said depressed member.

2. A replaceable shoe heel comprising a depressed member capable of being fastened onto the heel portion of a shoe, a plurality of oblong strips of resilient material mounted into said depressed member and arranged substantially in parallelism therein, the bottom portions of said strips being substantially in parallelism with the face of the depressed member, the sides of the said strips extending at an oblique angle toward the face of said depressed member, and means for detachably fastening said strips to said depressed member.

3. A replaceable shoe bottom comprising a base member capable of being fastened onto the bottom portions of a shoe, a plurality of elongated strips of shoe heel and sole material provided onto said base member and arranged in series thereon, means whereby said strips are interlocked into each other and means for removably securing the strips together and to the base member.

4. A replaceable shoe bottom comprising a depressed base member capable of being fastened onto the bottom portions of a shoe, a plurality of elongated strips of shoe heel and sole material provided into the depressed base member and arranged in series therein, the edges of certain said strips being flared inwardly andthe edges of certan other of said strips being flared outwardly, the inwardly flared and outwardly flared strips being relatively positioned with respect to each other alternately whereby the strips are wedged together into the depressed base member,

and means extending through the strips and connected to the base member whereby the strips are removably secured together and to the base member.
